For this exercise I have chosen a previously taken image:
This certainly leaves no doubt about the subject but hopefully is not just a shot of rain. It was taken from the inside of a tent - the other tents in the shot are just discernible enough for the reader to recognise. The low cloud dull sky adds to the effect.
The aim of the image is to hint at contrasting emotions of rain: on the one hand that it is unpleasant and restricting, particularly in an outdoors setting; on the other that the image is evidently taken from a position of shelter and relative comfort. the image could be taken from a car or a house, but that makes little difference to the effect.
